So after contemplating, I'm wondering what drawbacks there might be to building a pair if 8-9' cabs. 22X12X57 internal vol before any bracing, fill, or driver displacement. Probably around 8' net. I would mount a 2269 on the 22" 'side'. One each behind my Acoustat Monitor 3..(perfectly hidden), after I may be done listening to the York U15s whose bottom end needs extension, imo. How much does it matter the dimensions and/or placement of the driver? TIA.
